In the February number of this Journal the writer described a new settling tube for urinary deposits which possessed several advantages over the old method with conical test-glass and pipette.
The modern reader will probably be surprised at the comprehensiveness of the work, which, besides general diseases, includes considerable portions of physiology, physiognomy, ophthalmology, laryngology, otology, gynecology, neurology, dermatology, embryology, obstetrics, dietetics, urinary and venereal diseases, therapeutics, toxicology, operative surgery, cosmetics and even the hygiene of travel and the prevention of sea-sickness.
These are the degenerate string-like relics of the earlier umbilical arteries. Though in man and all the other Amniotes the primitive kidneys are thus early replaced by the permanent kidneys, and these alone then act as urinary organs, all the parts of the former are by no means lost. The nephroducts become very important physiologically by being converted into the passages of the sexual glands.
In the papillomas of the skin commonly known as warts the covering consists of epidermis; in those growing from mucous surfaces it consists of the epithelium covering the mucous membrane. When the surface epithelium projects as filiform processes, the tumour is called a villous papilloma, the best-known example of which is met with in the urinary bladder.
Man has faithfully preserved the main features of his stem-history in the ontogeny of his urinary and sexual organs. All the peculiarities of urogenital structure that distinguish the mammals from the rest of the Vertebrates are found in man; and in all special structural features he resembles the apes, particularly the anthropoid apes.
In more modern times Luschka and Sir Charles Bell considered that it is one of the uses of the nymphæ to direct the stream of urine, and Lamb from his own observation thinks the same conclusion probable. In reality there cannot be the slightest doubt about the function of the nymphæ, as, in Hyrtl's phrase, "the naiads of the urinary source," and it can be demonstrated by the simplest experiment.
"It is true," said the good old man, "and indeed, sir, as far as the charge of sorcery goes I was not guilty; as to that of being a pimp I cannot deny it; but I never thought I was doing any harm by it, for my only object was that all the world should enjoy itself and live in peace and quiet, without quarrels or troubles; but my good intentions were unavailing to save me from going where I never expect to come back from, with this weight of years upon me and a urinary ailment that never gives me a moment's ease;" and again he fell to weeping as before, and such compassion did Sancho feel for him that he took out a real of four from his bosom and gave it to him in alms.
De Brun du Bois-Noir speaks of the expulsion of extrauterine remains by the anus after seven years, and Heyerdahl after thirteen years. Benham mentions the discharge of a fetus by the rectum; there was a stricture of the rectum associated with syphilitic patches, necessitating the performance of colotomy. Bartholinus and Rosseus speak of fetal bones being discharged from the urinary passages.
Worms likewise drag an infinite number of dead leaves and other parts of plants into their burrows, partly for the sake of plugging them up and partly as food. The leaves which are dragged into the burrows as food, after being torn into the finest shreds, partially digested, and saturated with the intestinal and urinary secretions, are commingled with much earth.
In our plant-eating ancestors this rudimentary organ was much larger and had a useful function. Finally, we have important appendages of the alimentary tube in the bladder and urethra, which belong to the alimentary system. These urinary organs, acting as reservoir and duct for the urine excreted by the kidneys, originate from the innermost part of the allantoic pedicle.
